BURNER HEAD AND MOUNTING.

Application. med september 1s,- 1920. serial No. 410,67sf

To all whom z't may concern.'I

Be it known 'that I, JOSEPH T. VooRHEIs, a citizen of the United States,residing at Oakland, in the county ofAlamcda and .State of California,have invented a new change which cannot be accomplished with-1 outremoval of the burner. Such removal should be quickly and readilyaccomplished in many instances, for instance when maneuvering at sea,makinga landing or operating' under any condition where a full Y head ofste-am is necessary as the steam pressure may drop or the furnaces maybecome too cool, thereby causing flare-backs or other disastrousresults, etc.

One of the objects of the present invention is to provide a simple andsubstantial burner head` and mounting therefor, which will permitchanging or replacing of burners in a minimum of time and withcomparatively little effort on the part of the l'iremen.

V.Another object of the invention is to provide a mechanism whereby theburner and head may be quickly removed or replaced with relation lo themounting or support, said mechanism being readily accessible and in aposition where it will not be affected by leaking or escaping hot oil.

Another object of the invention is to prothe burner is automaticallyclosed when the burner is removed and conversely automatically openedwhen the burner is replaced.

Further objects will hereinafter appear.-

The invention consists of the parts and the construction, combinationand arrangement of parts as hereinafter more fully described andclaimed, having reference to the accompanying drawings, in which-- Fig.1 is a side elevation of the burner and mounting partially in section.

- Fig. r2'fis-,an end view of the same.

Refer'ringfto the drawings in detail, A indicates alpburner tube, 2 anozzle or' tip,

and V3 a head member to which the burner.

tube is secured as at 4.- The head member is provided with .an oil duct5 which communicates at one end with the burner tube and at the oppositeor lower end with an,

oil duct 6, which is formed in a mounting' or casting 7 provided as asupport for the burner head and tube. substantially L-shaped. 1t isprovided `with a handle extension 8 to permit it to be readily graspedand handled when removing or replacing the burner, and it is--otherwiseprovided with a seat section 9 which is.

ground to snugly engage a ground joint or seat 10 formed in the casting7. The burner tube isenclosed or partially protected from the heat ofthe furnace by anexterior tube 11., This tube'is secured Vto the casting7 by any suitable means, or as here shown by a set screw 12, the tubebeing secured against outward or endwise movement by. means of anannular flange 13, which also serves the4 function of centering andguiding the burner head and tube whenjreplaced; the burner head beingslightly enlarged at its upper end, as at 14' to permit it to he readilycentered with relation to the tube 11 when inserted. The casting 7 isother- The head member is wise. provided with an integral extensionbracket 15 on the forward end of which is formed a. lug 16. This lug isdrilled and threaded as at 17 to receive aclamping screw lhe inner endof this screw is slglnlyl concave and engages a centering boss 1!)forpied on the lower end of the head member-33. 'lhe screw 1S ispositioned in alignment with the center portion of the ground seats iland l() and is provided with a handle 19 so that sufficient pressure may4be exerted to form `a tight leakproof joint between the seatusections.The casting or mounting 7 is suitably supported and secured withrelation to the furnace front. It is connected with a source of oilsupply by means of a pipe 20; this pipe being provided with a valve 21whereby the oil supply to the burner may be regulated.' A

It has been found in actual practice that the firemen once in a whileforget to close the valve 21 when attemptine to remove the burner headand tube A. buch forgetfulness or carelessness on the part of the lire--men has in vseveral instances proved more or less disastrous as oilunder high pressure has escaped into the fire room and hasbeen lll)ignited by the fire in the furnace. VTo avoid such an accident I haveprovided a check valve 22. This valve-engages a seat member 23 formed inthe oil duct 6y and it is provided with a cylindricalhollow exten- 'sion24 which is engaged by theseat member 9 on the burner head. The hollowcylindrical extension 24 isv so long that it will hold the check valve22 away from its seat when theV burner head is in position, therebypermitting oil from the duct 6 to pass between the valve and the seatand to enter the oil duct 5 in the( burner1- head through radiallydisposed slots 25 formed in the extension 251. The check valve isengaged by a spring 26. interposed between the valve and a nut 2T andthe tension is such that the valve will instantly move forward againstits seat and shut oli' the oilsupply when the burn-er head is released.It is converselyv automatically opened when the burner head is replacedas -the cylindrical hollow extension 2t is so long that it will be4engaged by the seat section 9 and will thus force the valve rearwardlyto open position when the burner head is replaced. It can therefore beseen that the danger of escaping oil or hre is entirely avoided in thepresent instance' regardless of whether the valve 21 is closed or not asthe check valve will automatically close when the burner head is removedand will similarly assume an open position when the burner head isreplaced.

ln actual practice if for any reason it is necessary to change theburner, it is'accomplished by first closing the valve 21; secondlyreleasing the clamping screw 18; third swinging the burner head by grasping the handle 8 to the dotted line position shown at. S. This causesthe lower part ofthe burner head toswing out of alignment with the lug16 and thus permits the head, the burner tube A, and the nozzle carriedthereby to be retracted. `Wl1en it is desired io replace the same burneror a new burner, 1t isaccomphshed by' inserting the nozzle and tubethrough the exterior tube 11; the

tube and head being centered and guided` -while replacing the same bythe annular' fiange 13. The moment complete insertion has beenaccomplished, it will only be necessary to turn'the burner head and tubeto the vertical position shown in Figs. 1 and 2 and then to tighten theclamping screw and` again open the valve 21. While it is not absolutelynecessary to close the valve 21, due to the provision of the check valve22, it is obvious that it would be better practice to close the same asthe oil flow would instantly start with full force unless the valve 21is gradually opened. The annular flange 13 does not only center andguide the burner when it is reinserted, but it also serres as a pirotalpoint about which the This spring 1s Ahead is turned. It furthermoreinsures alignment of the two ground seats 9 and 10, thus insuringperfect positioningv of the same when the clam ing screw is tightened.To further insure a ignment of the ground Seats, I provide a side lug 28and a pair of stop members 29. These stop members insure alignment ofthe ground seats in a lateral direction and the annular flange 13insures alignment in a vertical direction. Iujury to the seat sections.is thus entirely avoided and alignment and centering of the same isquickly accomplished when replacing the burner.

iVhile certain features of the present invention are more or lessspecifically illustrated, I wish it understood that various changes inform and proportion -may be resorted to within the scope of the appendedclaims, similarly that the materials and finish of the several partsemployed may be such as the experience and judgment of the manufacturermay dictate or varying uses may demand.
